Porous Silicon Grinding

Porous Silicon - Siltronix Silicon Technologies

A porous silicon layer results from an electrochemical etching of a crystalline silicon wafer in a hydrofluoric acid based electrolyte. Various morphologies can be obtained depending on the type, the doping level, the crystalline orientation of the Si wafer and also on the electrolyte composition.

Porous Silicon as a Sacrificial Layer in ... - SpringerLink

This chapter discusses the use of porous silicon as a sacrificial supporting layer during silicon diaphragm formation by precision grinding. Unsupported silicon diaphragms formed by grinding exhibit post-grinding shape distortion dependent upon diaphragm thickness and diameter.

Grinding Media - Milling Balls - Ceramic Grinding Media ...

Grinding media are the means used to crush or grind material in a mill. It comes in different forms such as alumina oxide balls , ceramic cylinders, or soda lime glass. At Norstone Inc., we offer all types of medias used for grinding, deagglomeration, polishing, deburring, fillers, proppants, spacers, refractory beds and shot peening.

1 Fundamentals of Porous Silicon Preparation

silicon; preparation of porous silicon thus requires an additive in the solu-tion to dissolve the oxide and allow electrochemical oxidation to continue. The Si – F bond is the only bond stronger than Si – O, and it is the Si – F bond enthalpy that drives the main stone dissolution reaction used to make porous silicon.
